Dissatisfied customer

I bought a new decoder August 2022, the person sent to install it decided to install Family instead of Compact. I was billed for his mistake, I called MultiChoice to cancel it that said it's canceled. My subscription was disconnected was told to pay R508 paid it and was told the Family subscription is canceled. January 10 2023 my subscription is disconnected again, I'm told the money I paid last month paid for the Family subscription that I called with my airtime to cancel. R310 is due before my subscription can be reconnected, how is it fair that I have to pay for MultiChoice mistake over and over again??
